Cant Duel boot with windows 7 - ocb loadimage failed - unsupported

Hi everyone.

I managed to install my Hackintosh and it works fine.

The OpenCore boot manager loads and i can select either mac, or windows.

They are both installed on the same drive, but on seperate partitions.

The problme i have is, that windows refuses to load. I have managed to install it via the command line and followed this tutorial...

https://old.reddit.com/r/Hackintosh/comments/jdojia/dual_booting_windows_macos_same_drive_zero_risk/

and this youtube guide (from the same tutorial)

Windows seemed to install intself, and has the syetem partition, msr, and windows, which shows up as the c: drive.

I followed all the documentation, but can not boot in to windows.

When i boot from OpenCore i get the "ocb loadimage failed - unsupported" message, and when i boot from windows boot manager i get.. "Reboot and select proper boot device".

So clearly, it cant find windows, but i dont understand why not.

On OpenCore boot manager i get 3 options...

  1. windows
  2. windows
  3. macos

I have windows listed twice as i copied the windows efi from its own efi partition, to the main one, so now it shows up twice! neither work.

Does anyone have any clues please? Many thanks
